Oof! Poor Koala Runs Smack Into a Mean Tree

This adorable koala named Mason at Australia's Port Stephens Koalas got a little too worked up while playing and ran right into a tree.

The impact of the hit catches Mason off-guard, but he quickly bounces back and heads out for more. Perhaps he's headed for a shrub or a ficus or something that can't unleash its fury so dominantly upon him. Hang in there, Mason -- you nay have taken it on the chin, but you're still plenty cute and that's only going to help.
